Patent EP-0325203-A1 (EP)
Inventor: AUER HEINZ DR DIPL-PHYS
IPC: C01G45/02
Filed: 1989-01-17
Abstract: In making solid electrolyte capacitors, the pores in the valve metal sintered bodies formed are first almost completely filled with manganese dioxide which is produced by pyrolysis of solutions containing manganese nitrate. The sintered bodies are then immersed in a manganese nitrate melt with low water content which may optionally contain added manganese dioxide powder and/or silicon dioxide powder. The bodies are then placed in an oven, and first heated to approximately 100 DEG C in dry air. Then fine water droplets are applied to the surface of the heated sintered bodies and the pyrolysis is completed in a flowing steam mist at temperatures of 200 to 350 DEG C. The residual currents IR of such capacitors (curve 1) reveal no rejects after 1,000 hours continuous testing at 85 DEG C and 95 % relative humidity, whereas conventionally produced capacitors (curve 2) exhibit almost 15 % rejects. …<IMAGE>…

Abstract: A method and apparatus for recovering heat energy from an exhaust gas containing a corrosive constituent which is condensable at and below a corrosive condensation temperature by passing said gas successively through first and second heat exchangers each connected to transfer heat to a fluid, said second heat exchanger containing a corrosion-protection material having a material limit operating temperature exceeding said corrosive condensation temperature, the flow rates and temperatures of said exhaust gas and the fluid being heated by each heat exchanger being arranged so that passage of said exhaust gas through said first heat exchanger cools said exhaust gas from a first temperature to a second temperature which is below said material limit operating temperature but above said corrosive condensation temperature, and passage of said exhaust gas through said second heat exchanger cools at least a portion of said exhaust gas from a temperature above said corrosive condensation temperature to a temperature below said corrosive condensation temperature whereby said corrosive constituent does not condense in said first heat exchanger, said corrosive constituent does condense in said second heat exchanger, and the cooling of said gas in said first heat exchanger prevents thermal damage to said second heat exchanger.

Abstract: The invention comprises a method and a device for fault lo­cation in case of a fault appearing on a power transmission line between two stations (P, Q) and when capacitive measur­ing transformers are used for voltage measurement. The fault location is performed on the basis of a distance protection equation in which the voltage measured at the measuring sta­tion, in addition to the voltage drop (U PF ) across that part of the line which lies between the measuring station and the fault location (F) and the voltage drop across the fault re­sistance, also comprises a voltage which represents the mea­surement error voltage which is introduced by the capacitive voltage measuring transformer. The equation is solved with the aid of linear regression technique. With knowledge of the impedance (Z PQ ) of the faultless line and the current in question, the fault position (α = 0 - 1) is determined.

Abstract: Packing containers and packing container blanks of the type used for the packaging of e.g. milk and juice often are of the so-called gable-top type, the top closure also serving as an opening arrangement with a pouring spout which can be folded out. The parts (9, 10) forming the pouring spout (14) may be coated partly with a seal-preventing substance so as to make it possible for the pouring spout to be detached and let out in spite of the heat-sealing of the top. The seal-preventing coating (15) in accordance with the invention is covered by a film (16) which extends along the upper edge region of the packing container (1), which provides a better defined sealing strength, a tighter top seal, and protects the said coating (15) both before and after the conversion of the packing container blank (2) to packing containers (1)

Abstract: A device for controlling an access operation of an information recording and reproducing device to a target position for rough access in a disk-shaped recording medium (101) prior to a precision access to a final target position, including a head (102) carried by an actuator (201, 103), a scale (203), a counter (204), a comparator (212), a timer (211), and a controller (209). The scale (203) emits pulses while the head (102) is traveling. The counter (204) counts the pulses and then provide the count to the comparator (212), which calculates a difference between the count and an access distance to be traveled for rough access and then compares the difference with a value which is determined in advance in consideration of a tolerable error. The comparison result is input into the controller (209). If the comparison result received when the timer (211) finishes measuring the specified time indicates that the difference between the access distance and the count falls within the change of the predetermined value, the controller (209) decides that the actual rough access operation has been normally finished as desired, thereby decreasing a wrong judgement with respect to finish of the rough access irrespective of a value counted by the counter (204).

The structure is in the shape of a right circular cylinder with a plurality of internal cells (16, 22, 26) extending along the substrate and an opening on both ends. In order to provide maximum crushing strength of the structure, as well as permitting uniform intercell wall thickness at the downstream face of the extrusion die which forms the structure, the majority of the cells are formed in the transverse cross section of a truncated (circular) sector and have the property that they each possess the same hydraulic diameter, although not all are of the same transverse cross sectional shape. An extrusion die is provided which is formed by a plurality of concentric, collared tubes (40, 50,60) provided with longitudinally running slots (48, 58, 68) in the tubes and notches (44, 54, 64) on the collars (42, 52, 62), the tubes being radially spaced from each other.
